Pitch Darker is a frontend for exploring and playing modern interactive fiction on an 8-bit Apple II. Some notable features:
UI for browsing all games and setting global options (pictured)
Double hi-res artwork
On Beyond Z-Machine! interpreter runs games directly from ProDOS (no swapping floppies!)
Pitch Darker requires a minimum of 128K RAM and an enhanced Apple //e, Apple //c, or Apple IIgs.
Additionally, you will need a mass storage device that can mount a 32 MB ProDOS hard drive image. This supported by all major emulators; if you are lucky enough to have a real working Apple //e, you can mount it with a CFFA3000 or similar adapter.
